Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment	This unit of competency could be assessed in the workplace or a close simulation of the workplace environment providing that simulated or project-based assessment techniques fully replicate plumbing and services workplace conditions, materials, activities, responsibilities and procedures.
Critical aspects for assessment and evidence required to demonstrate competency in this unit	A person who demonstrates competency in this unit must be able to provide evidence of: locating, interpreting and applying relevant information, Australian standards and specifications for the installation of Type B appliance flues applying safety requirements throughout the work sequence, including the electrical safety requirements and use of personal protective clothing and equipment given the plans, specifications and regulatory authority approval, installing a mild steel flue from a boiler flue spigot to terminate above the roofline, ensuring: application of sustainability principles and concepts throughout the installation correct identification of location, design and details of proposed installation correct selection and use of appropriate processes, tools and equipment completion of all work to specification compliance with regulations, relevant Australian standards and organisational quality procedures and processes communicating and working effectively and safely with others.
Context of and specific resources for assessment	This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints. Assessment of essential underpinning knowledge will usually be conducted in an off-site context. Assessment is to comply with relevant regulatory or Australian standards' requirements. Resource implications for assessment include: an induction procedure and requirement realistic tasks or simulated tasks covering the minimum task requirements relevant specifications and work instructions tools and equipment appropriate to applying safe work practices support materials appropriate to activity workplace instructions relating to safe work practices and addressing hazards and emergencies material safety data sheets research resources, including industry-related systems information. Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.
Method of assessment	Assessment methods must: satisfy the endorsed Assessment Guidelines of the Construction, Plumbing and Services Training Package include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application reinforce the integration of employability skills with workplace tasks and job roles confirm that competency is verified and able to be transferred to other circumstances and environments. Validity and sufficiency of evidence requires that: competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice, with a decision on competency only taken at the point when the assessor has complete confidence in the person's demonstrated ability and applied knowledge all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence. Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed. Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.
